Based on the symmetry of a one dimensional chain of spheres, spherical surface waves are considered to be responsible for the energy transport. A simple mathematical model is set up to describe the energy exchange during consequent granule-to-granule interactions. Experiments on a two-sphere setup support this model.Amer Inst Physics0094-243X978-0-7354-1166-1Powders And Grains 2013Conference Papers10.1063/1.4811997
